Waterproof rucksack/backpack recommendations

[458bhp]

About to start to commute on the bike and need recommendations on which waterproof rucksack/backpack to get!?! Before anyone suggests it, I don't want panniers or a waterproof cover!

I'll be carrying a large tablet (Surface Pro type) and clothes/jacket/shoes so must be fully waterproof, lunch/dinner and a shaker (protein).

Will also be cycling for the first time in the dark so would like to be clearly seen.

So far my favourite is this one:

Anything else I should consider?

If you want to be seen - http://www.provizsports.com/en-gb/reflect360-cycli...

That's quite a list to carry each day, is there an option to leave some shoes/clothes in the office?

You should consider rethinking your aversion to panniers, my friend.

The bike is better designed to carry weight than your back.

I was looking at these a week or two ago and plumped for Lomo day sack in black at £30

Also considered the Decathlon itiwit roughly the same price, though I could have got it in store and saved on the postage for the Lomo https://www.decathlon.co.uk/20l-watertight-backpac...

I have some ortlieb panniers already, but do much of my commute on the train/walking and need something really comfy to carry around. To echo earlier comments though, I don't wear it on my back on the bike, it goes in the super cool basket I have on the top of the rack at the back. I don't need the bag to be hi-viz, just waterproof. I read a comment on a review that said the pro-viz one wasn't long-lived.

Previously I had been using an old berghaus rucksack I'd had for 25 years - sadly no-longer remotely waterproof. So I kept a hi-tech bin liner in it and put it inside when the rain was bad. That worked fine for the most recent November, December, Jan and Feb - just a bit of a fiddle and I felt I'd saved the train money enough to treat myself to this and some proper mudguards.

Some reading for you here - comments probably as useful as the article: http://www.londoncyclist.co.uk/waterproof-cycling-...

Cheers guys, with regards to the reflect360 http://www.provizsports.com/en-gb/reflect360-cycli... is it actually waterproof, it says this in the blurb 'Highly water-resistant material: 1500mm water column'. Not sure what that means exactly?

To answer my question, I sent an email to them 20mins ago thinking I won't get a response until Tuesday, just received this:

'The rucksack will withstand solid rain but will not be able to be submersed. This is why it is water-resistant and not stated as waterproof'.

Like the look of the Lomo.

Remembered I have some of their dry bags for boating.

I used to use these on the motorbike prior to moving to hard luggage, bit more pricy though.

With what you listed carrying, I wouldn't rule out pannier/porteur rack.
